Web Developer Features: Firefox 3.5 is the fastest and have most advanced Web Developer Features

pen Video and Audio:Online media gets a major upgrade with Firefox 3.5. It includes the world’s first implementation of HTML 5 audio and video support (Ogg Vorbis and Ogg Theora), allowing web developers to include rich media that’s controlled using JavaScript, HTML and CSS instead of by proprietary technologies. View documentation.

XHR Firefox 3.5 supports cross-site XMLHttpRequests, which means your Web applications can now access material from other servers (as long as the servers are configured to allow it), thus paving the way for new mashups and other online collaborations. View documentation.

Downloadable Fonts: Web developers and site designers can now get a more consistent look across all platforms by using downloadable TrueType and OpenType fonts in their designs instead of relying on the fonts installed on the user’s local machine. View documentation.

TraceMonkey: Knowing that users have the benefit of Firefox 3.5’s dramatically improved TraceMonkey engine, Web developers can build JavaScript-based applications and sites that are faster and more responsive than ever (see Performance section above for more details). View documentation.

Location-aware Browsing

In Firefox 3.5, users can share their location with requesting websites, allowing developers to customize their applications so they deliver more useful, more relevant output. Learn more about this feature.

Native JSON

Firefox 3.5 has improved support for JSON, with native handling of JSON objects to make encoding and decoding JSON faster than ever before. View documentation.

Web Worker Threads

Multithreading support finally comes to the Web through the new Web Workers feature, which allows JavaScript code to spawn off threads to handle tasks in the background. Web applications can now take advantage of modern multicore processors. View documentation.

Media Queries

Support for CSS 3 media queries lets style sheets define content appearance more precisely. They now take an intelligent look at the details of whatever device is rendering your content, giving you more control over the final user experience. For example, you can render your site in one way for color printers and another for black and white. View documentation.

Offline Support

Firefox 3.5 supports HTML 5 offline resource caching. This lets Web applications cache static content on the user’s system for reuse instead of requiring it to be reloaded over the network each time it’s needed. The result: much faster web application load times. View documentation.

More Developer Goodness

In addition to these other features, Firefox 3.5 has updated or added other CSS properties, DOM events and tools to build even more beautiful and responsive web pages. Check out the full list on our 3.5 developer’s page.
